The DHT11 is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and sends the data to a digital pin on the ...

This Arduino project reads temperature and humidity data using the DHT11 sensor and prints the output to the serial monitor. Connect your DHT11 sensor to the Arduino as per the wiring table. Upload ...

Furthermore, as the DHT11 sensor has a complex single-wire communication protocol, I hired additional help from a very popular library — the DHT Library — to simplify my Arduino code.
